The black tower measures 12.76 inches high, 6.06 inches wide and 11.53 inches deep, weighing 12.02 lb. Front ports provide two USB 2.0 sockets, one USB 3.2 Gen 1 Type-C port, one USB 3.2 Gen 1 Type-A port and a headset jack. The rear panel adds a DisplayPort 1.4, an HDMI 2.1, two USB 3.2 Type-A ports, two USB 2.0 Type-A ports and a gigabit RJ-45 jack. A Kensington lock slot and padlock loop are also fitted.

RTX 3050 graphics with Wi-Fi 6 and Bluetooth 5.4

An NVIDIA GeForce RTX 3050 with 6 GB of GDDR6 memory drives the display outputs. Wireless connectivity uses a MediaTek Wi-Fi 6 MT7920 2x2 card supporting 802.11ax MU-MIMO alongside Bluetooth 5.4. The configuration targets everyday productivity and light creative workloads rather than sustained high-end gaming or heavy compute clusters.
